Why would a VSI read backwards? There is only 1 port in the back of the VSI  for connecting to the static source.

  

 When the plane goes 'up' the VSI says it's descending and visa-versa.

  

 Can this be repaired or reversed to read properly?

  

 Thanks in advance,

I think you need to fly  below sea level.  Or maybe inverted?  I know, you need to fly in the  southern hemisphere.

  

 Seriously, it would seem  to be mechanically mis-assembled, as it is hard to imagine what else would do  it.  If it were connected to the pitot, it would misbehave wildly, but not  as you describe.

If the port is blocked, and the air pressure is changing within the body of the instrument...leak in the body or glass face.

 I'm going to tak. a wild guess.  You've got the VSI hooked up to the static port.  What's the answer???

Rick, I once had a VSI which about drove me crazy.  Turns  out I cracked the case when I installed it in the instrument panel which caused  strange indications.

Again, this VSI doesn't behave erratically or give 'strange'  indications......it's works as advertised....only it reads sdrawkcab  (backwards).

Turn it 180 degrees in your panel!

You have to fly with the wheels side down and the

canopy side up for it to work properly.

Had the shot and took it:D
